You can definitely tell this is a high quality system just from the way it is packaged. Easy to install with basic hand tools and a few hours in the garage. Big increase in turbo noises both induction and blow off sounds. I personally didn't notice obvious performance gains but multiple dyno runs completed by others on FL5/DE5 confirm the increase in power which is great for supporting other planned upgrades (intercooler, turbo and downpipe).
Got my exhaust sounded like it should. No leaks. Great packaging.
The obvious mod if you're swapping the intercooler. Combine that with the Intake box and it's like taking the muzzle off a howling dog! You can practically feel the breeze. No instruction but one tip is you're unsure of orientation, Logo always faces up for promotion purposes.
Easy installation and product is good quality. Highly recommend if you don't want to spend much more on other premium alternatives
